A Successful, Diverse Disease-Associated Lineage of Nontypeable Pneumococci That Has Lost the Capsular Biosynthesis Locus
1 Mar 2006
Abstract excerpt
Streptococcus pneumoniae strains which fail to produce a polysaccharide capsule are commonly isolated from carriage and disease contexts. Here we use a multilocus approach to distinguish genuine nontypeable pneumococci from closely related nontypeable streptococcal isolates in a data set of 121 untypeable pneumococci from nasopharyngeal swabs and middle ear fluid of Finnish children and demonstrate that 70 of...
